Existence loves freedom, celebrates freedom, it bestows freedom on each and every aspect which belongs to itself. And you belong to existence. You are the peak of life on this Earth, and God never intended that you be miserable.

Mother Nature knows best. This is obvious when we see animals fighting instinctively for their survival. We are mammals as well, so let us stop referring to sports when speaking about self- defence. The reptilian mindset with its simple and effective blows is the best way of retaliating against your assailant(s) if you cannot run away.
